I Did Something Stupid (Wearable UX)

I did something stupid today. I disagreed with one of the leading experts in interface design, mobile, and specifically the soon-to-be-released Apple Watch.

The argument is over a chart Luke Wroblewski (@lukew) posted about the distraction factor of a smart phone vs. a smart watch, indicating use of a smart watch lets you be "more connected to the people around you..."

There are two problems here:

First, the chart is fiction. It measures "real life" vs. "lost in phone" — concepts of psychological state which are hard to define, never mind measure. Perhaps there is some real data behind the charts, but if so the labels do it no justice. I suspect the diagram is more a representation of belief or expectation than fact. In which, why is it a chart?

Second, it is not the phone that this the point of distraction. It is the information on the phone — phone, watch, iPad, eye piece, etc — and not the device itself that is the distraction. So putting the notifications on the wrist may reduce the time it takes to switch from in-the-present to in-the-data, but it does not alter the distraction factor that data provides, whether it is in my pocket or on my wrist.

One of the most disturbing studies in this area is recent research into the use of "hands free" devices while driving. I would equate Luke's proposal that data-on-the-wrist is less distracting from "real life" to the arguments that hands-free phone technology is less distracting to driving. However, the National Safety Council published a report arguing that hands-free does not significantly reduce the risks to distracted driving.

"Hands-free devices often are seen as a solution
to the risks of driver distraction because they help
eliminate two obvious risks – visual, looking away
from the road and manual, removing your hands
off of the steering wheel. However, a third type of
distraction can occur when using cell phones while
driving – cognitive, taking your mind off the road.

The amount of exposure to each risk is key. Crashes
are a function of the severity of each risk and how
often the risk occurs. Most people can recognize
when they are visually or mechanically distracted
and seek to disengage from these activities as
quickly as possible. However, people typically do not
realize when they are cognitively distracted, such as
taking part in a phone conversation; therefore, the
risk lasts much, much longer. This likely explains
why researchers have not been able to find a safety
benefit to hands-free phone conversations. "

One argument is that the data on the smart watch is primarily uni-directional — not requiring a response. For example, a "be there in 5 mins" message But if that is the case, how are those messages being generated? By smart watch wearers pulling out their phones to push the messages? And the fact that the message doesn't require a response doesn't mean it doesn't require cognitive effort — and distraction from current activities — to process it.

Wearables such as smart watches may eliminate the time and effort required to pull out the smart phone. But I have my doubts (unfounded, uninformed, as they may be) that they actually reduce the distraction that modern streaming personal data causes.
